This shows what is on the Canadian trademark register and what looks or sounds similar. It is not legal advice and not a clearance search: it cannot say whether a name is safe to use or would conflict with another mark. A trademark agent can.
Register as of January 22, 2025: CIPO's latest public data release (Open Government Licence – Canada). Marks filed or changed since then are not here yet. Check the current record on CIPO's own database before relying on it.
